After you configure periodic LSP tracert and the mpls te failure-action teardown command for an MPLS
TE tunnel, once an RSVP-TE tunnel failure occurs, the periodic LSP tracert function can detect the failure,
and if RSVP does not reestablish the RSVP-TE tunnel within a specific period of time, MPLS TE removes the
failed RSVP-TE tunnel and then reestablishes it.
To configure periodic LSP tracert for an MPLS TE tunnel:
Ste

Command
Remarks
1. Enter system view.

2. Enable LSP verification and
enter MPLS LSPV view.
mpls lspv
By default, LSP verification is
disabled.
For more information about this
command, see MPLS Command
Reference.
3. Return to system view.

4. Enter the tunnel interface view
of an MPLS TE tunnel.

5. Enable periodic LSP tracert for
the MPLS TE tunnel.
mpls te periodic-tracert [ -a
source-ip | -exp exp-value | -h
ttl-value | -m wait-time | -t time-out
| -u retry-attempt ] *
By default, periodic LSP tracert is
disabled for MPLS TE tunnels.
6. Configure MPLS TE to tear
down a failed RSVP TE tunnel
and reestablish it.
mpls te failure-action teardown
Optional.
Not configured by default.
Enabling MPLS TE statistics
To use display commands to view RSVP-TE tunnel statistics, you must first enable MPLS TE statistics by
using this configuration task and set the statistics reading interval by using the statistics interval
command in MPLS view. For more information about the statistics interval command, see MPLS
Command Reference.
To enable MPLS TE statistics collection:

You can use the display mpls statistics lsp command, the display mpls statistics lsp in-label command,
and the display mpls statistics tunnel command to view the MPLS TE tunnel statistics. For more
information about the statistics, see MPLS Command Reference.
